with an inclined or angled table upon which 'l the meat is fed forwardautomatically and is cut by a rotating circular knife which is movedthrough a curvilinear path so as to cut the meat from its upper enddownward the slices as they are severed falling down and away from themeat.

The machine comprises other novel features of construction ashereinafter pointed out in the claims.

The rotary knife is so made or arranged or the table is so arrangedrelatively with the knife, that the latter only comes in conmy improvedmeat slicing machine showing.

gear f from a shaft g driven by a hand wheel g1 or a motor or otherwise.

The table e which is Xed to or made one with the base is inclined upwardat an an le, as shown clearly in Figs. 1 and 3, being preferably made ofsomewhat triangular form and bolted to the base. It has, at its lowerend, a projecting part 1 which extends outward. at or about rightangles. The front part of this inclined table has a series of shallowgrooves 2 which assist in holding and guiding the meat while being cut.Upon. the inclined table and conforming therewith is a slide 3 having "apart at or about right angles covering the similar part of the table andthis slide (or meat plate as it is usually called) with the meatthereon, is fed forward, as usual, intermittently, by means of a screw 4the ends of which pass through bearing brackets 5, 6, secured to theinclined table and project-ing upward from the apex thereof. Secured tothe slide are two brackets 7, 8, having enlarged part-s surrounding andsliding on the screw 4 and which are connected together by a bridge 9having a pin 'l0-therein with the usual half nut (not shown) forengagingthe screw. this-half nut being moved into and out of engagementwith the screw by means of a cam lever 12.

The screw 4 is turned so as to give the intermittent forward motion tothe slide by means of a cam 13 on the shaft 14 the cam,

`as it rotates, acting on 'a roller 15 at the lower end of a rod 16which latter, at its upper-end, is jointed to a bell crank lever 17 foroperating the feed pawl 18 and ratchet 19 on the feed screw. The feedcan be regu lated by'means of the cam 20, link 21, and slide 22 in thesame manner as in W. A. Van Berkels specification No. 920506 dated 4thMay, 1909. The rod 16 is held in position by a radial arm 23 pivoted at23a which may be weighted so as to retain the roller 15 in contact withthe feed cam 13.

The knife b is carried at the upper end of I a strong gear case or frame25 having a nickel plated front 26 and which is secured to a sleeve 27(see also Fig. 5) surrounding the shaft l and 'Working in bearings 28,29. The shaft runs in ball bearings 30, 31, within the sleevewhichlatter and also the gear case is rocked by the arm 32 of Athe sleeveconnected by a rod 33 to the disk 34 keyed on the shaft 14 and operatedthereby. The

shaft 14 is rotated by the spur gearing 37,

38, 39, from the shaft d. To counteract the Weight of the knife andthereby reduce the effort required to drive the machine a torsion spring35 is provided which, at one end, is connected to the sleeve and at itsother end to the bearing 28. Means may be provided for tightening up thespring if so desired.

rlhe knife sharpening device I may be such as described in thespecification of WV. .L Van Berkels Patent No. 947,606, dated thJanuary, 1910 and isfmounted on the fixed standard or knife case 36.When it is desired to sharpen the knife the idle gear Wheel 38 is pulledalong its pin 40 out of engagement by means of the knob 4l so that themechanism .for swinging the knife is stopped and the swinging arm 32 canalso be locked by the spring pin 42 operated by the cam lever 43. Whenthis has been done v the shaft g and knife can be rotated so as to besharpened in the usual manner by the Sharpener.

44 is the meat clamp.

'Ihe knife case 36 may have the outer side 36a of glass or mica.

rlhe knife is circular as before stated and it is adapted to contactwith the meat only at its periphery While cutting. The peripheralcontact can be effected by making the knife dished or concave or bymaking it flat and arranging it at an angle to the table or the table atan angle to it.

The incline of the table is about at an angle of forty-five degrees andif produced Aforms a chord to the arc described by the center of therotary knife, so that as the revolving knife descends upon the meatwhich is clamped in the meat clamp, said knife will begin cutting intothe upper corner of the meat and compress the meat against themeatfplate, thus insuring a clear cut through to the lower corner andinsuring against tearing or shredding of the meat at the end of the cut.As the slice is severed from the piece of meat, it will fall over, awayfrom the piece and away from the knife, whereby all friction of the`slice against the knife will be avoided, rendering cutting easier andavoiding tearing of the meat-by itsadhering to the knife.
